Clever uses of InvokeDynamic

[MacGregor, Duncan (GE Energy)]

Really it's similar to lazy constants, but we use invokeDynamic for
global variable access which we have a lot of since our language is
exemplar based we have a lot of globals that hold those exemplars. The
name of the global is passed as an argument to the bootstrap and this
returns a constant call site that gets or sets the value in a bound
storage cell.

Subject: Clever uses of InvokeDynamic

I'm filling out the remaining slides in my JAX keynote on InvokeDynamic,
and I'm interested in additional "clever" uses of invokedynamic folks
have discovered.

I have included the following, which we make use of in JRuby:

* Dynamic invocation (obviously)
* Lazy constants
* Multiple dispatch

I'll also make a brief mention of MethodHandle as a replacement for
java.lang.reflect stuff.

Other good ones for a room full of people learning invokedynamic for the
first time?
